Why 1970? — Under the Hood
Unix time counts seconds since the epoch — 1970-01-00 in Bell Labs' original reckoning — chosen because it postdates most then-living systems and predates the C language standardization. Stored as a signed 32-bit integer it overflows in January 2038 (the famous Y2K38 bug), which is why modern systems moved to 64-bit timestamps.

It measures from "now", so it drifts as time passes.
